Got a new GSO CF RC8 on Friday and gave it a test run on the weekend.

On Sat arvo, a mate collimated it for me with a TAK microscope thingy, and CCD inspector says it looks pretty good, with a minor tilt issue that will take time to resolve until the bog standard, (substandard) focusser is upgraded.

... and I discovered that urgently need to source a dew heater for the secondary!

However, despite my PA being spot on as per my usual methods - I noted that my PHD graph was up and down like a kids birthday party at Bounce!

It's normally a pretty flat line, (as in the patient's dead doctor...) I'm using a QSI 683 with a Lodestar OAG on an EQ6.

So does anyone have recommended settings for PHD at longer Focal Lengths? (I use PHD 1 - original flavour)

Cheers

Andy
